Question

a rotation takes triangle a to triangle b. well call this transformation 1. describe the rotation that takes triangle a to triangle b. transformation 1: rotate around point

Explanation:

Step1: Identify the center of rotation

By observing the figure, we can see that the point around which the rotation occurs is point \(Y\).

Step2: Determine the angle of rotation

We can count the number of grid - squares and the direction of rotation. Triangle \(A\) rotates 90 degrees counter - clockwise around point \(Y\) to get triangle \(B\).

Answer:

Rotate around point \(Y\) 90 degrees counter - clockwise.
